GS1 data

GTIN (01)Expiration YYMMDD (17)Lot (10)Serial (21)

GS1 variable-length fields need careful scanner validation. Use this as a starting point.

How to use this tool

Start with sample data

Use the default values to understand the expected ZPL shape.

Adjust for your printer

Check label size, DPI, barcode data, and printer-specific settings before production.

Preview or copy the result

Use the main ZPL Viewer for final visual checks whenever the tool generates ZPL.

Frequently Asked Questions

No. It helps catch obvious layout and data mistakes before final hardware validation.

Treat them as a starting point. Review printer model, DPI, media, and business data before production printing.

Some printer-language conversions are not one-to-one. A clear migration map is safer than pretending every ZPL command has a perfect EPL or CPCL equivalent.
